Steel mesh edge rubber waterstop with self-adhesive layer and manufacturing process thereof

Abstract

The invention relates to a steel mesh edge rubber waterstop with a self-adhesive layer and a manufacturing process thereof. The steel mesh edge rubber waterstop comprises a rubber body. A round hole for meeting the expansion and contraction of deformation joints of a building is formed in the middle of the rubber body, and wing plates of the rubber body are arranged on two sides of the round hole.The steel mesh edge rubber waterstop is characterized in that steel mesh edges are sandwiched in the middle of two sides of the wing plates in a compounded mode, a fiber interface reinforcing layer is arranged on the surfaces of the wing plates in a compounded mode, the surface of the fiber interface reinforcing layer is coated with a synthetic rubber self-adhesive layer, and the synthetic rubberself-adhesive layer is covered with isolation paper. The steel mesh edge rubber waterstop with the self-adhesive layer has the advantages that a rubber material is adopted to improve resistance to various chemical media corrosion of the waterstop, and the durability is improved; the fiber interface reinforcing layer is coated with the synthetic rubber self-adhesive layer to improve the insufficient bonding between the weak interface of the rubber surface and cement concrete; the physical inlay between the steel mesh edges and the rubber material and the cement concrete improves the bonding strength of the steel mesh edges and the rubber material and the cement concrete. According to the manufacturing process, the steel mesh edge rubber waterstop is formed by one-step molding in a rubber extruder assembly line, the process is simple, and the efficiency is high.

Description

technical field [0001] The invention relates to a steel mesh edge rubber waterstop with a self-adhesive layer and a manufacturing process thereof, which is mainly used for waterproofing deformation joints of buildings. Background technique [0002] Building deformation joints are divided into three types according to the different external destructive factors, namely expansion joints, settlement joints and anti-seismic joints. [0003] In industrial and civil buildings, due to the influence of factors such as temperature changes, uneven foundation settlement, and earthquakes, additional stress and deformation will occur inside the building structure. If it is not handled properly, it will cause damage to the building, cracks or even collapse. Affect use and safety. The solutions include: strengthening the integrity of the building so that it has sufficient strength and rigidity to overcome these destructive stresses without causing damage; disconnect the structure in advanc...
